Cultivation: This plant
isn't famous
for being easy to cultivate, but in good conditions
with excellent
ventilation,
it grows without difficulty. It is especially sensitive to over-watering.
So careful watering and an open
mineral
potting soil are a must.
Avoid
the use of
peat or other
humus sources in the
potting mixture.
Don't add
limestone
to the potting mix, which must be moderately acidic.
Can be sensitive to frost (but some populations are resistant to
-10° C). Requires
maximum
sun exposure
to reach its full potential.
and in order to
achieve success in
flowering.
A winter rest that allows the plant to shrivel (perhaps losing up to
25% of its summer height) will encourage flowering and long
term
survival. Be careful to encourage slow growth.
Propagation: Seeds or
offsets.
